I don't know this actual equipment, and the pic isn't high enough res. to
tell, but it looks like a combined oscillator and audio level measuring
meter - rather like the Ferrograph test set that we lesser mortals got to
play with. Which I still use for many things - despite modern devices
being smaller and more accurate. At least it doesn't have a keyboard or
mouse. ;-)
